The Wall by Marlen Haushofer

A woman goes to the Austrian mountains to spend a few days in a hunting lodge with her cousin and his wife. When the couple fail to return from a walk, the woman tries to go into the village to look for them. Instead she comes across a transparent wall behind which there seems to be no life. Trapped behind the wall, a result of a too successful military experiment, she begins the arduous work of not only survival but self-renewal. The Wall is at once a simple document of potatoes and beans, of hoping for a calf, of counting matches, of forgetting the taste of sugar and the use of one's name, and simultaneously a disturbing meditation on our place in the natural world.
